Allocated but Unused LUNs
Use Search to find a template, report or dashboard by name. Search is case insensitive, supports partial entries, and will display a list of potential matches.
As you enter the name in the Search field, up to 10 potential matches are displayed. If the template, report or dashboard is shown, you can select and run it directly from the match list. You can also click All Items in the match list to go directly to the Search Results.
StorageConsole provides different navigation options to slice and examine your collected data. You can explore the data by using the APTARE customizable report templates or by using parts of your IT infrastructure as entry points. The Inventory Navigator serves as a browser for your infrastructure by object type. See also Exploring Your Inventory.
Use the Reports tab to examine the StorageConsole catalog of templates, dashboards and reports - organized by products along with user-created, and system folders. This report is located here:
These are LUNs that have been assigned to a host, but the host has not been placed into a volume group, or a partition has not been created. The array has created the LUN and the storage path exists, making the host and host port information available to Capacity Manager. However, the host storage details—disks, partitions, and volume groups—are not available for the host associated with the storage path.
For HP 3PAR: LUNs refer to Virtual Volumes and Volume Groups refer to Common Provisioning Groups.
NOTE: The list of Allocated, but unused LUNs includes LUNs that have been allocated, discovered, but not yet mounted. The list of Allocated, but undiscovered LUNs includes LUNs hat have been allocated, but undiscovered.
Additional details can be accessed via the following drill-down links in the report:
• Array Group - Array Group Details
• Array Name - Array Capacity and Utilization
• Host - Host Utilization Detail
Name
Name of the LUN that has been allocated, but unused. For HP 3PAR: LUN refers to Virtual Volume (VV).
RAID Type
The RAID level on the LUN. When the RAID type is Disk, there is no RAID protection. For HP 3PAR: LUN refers to Virtual Volume (VV).
Array Group
The group to which the array belongs.
Storage Array
The storage array for this LUN. For HP 3PAR: LUN refers to Virtual Volume (VV).
Capacity
The total capacity (used and unused) of the LUN. For HP 3PAR: LUN refers to Virtual Volume (VV).
Estimated Used
LUN estimated used. For HP 3PAR: LUN refers to Virtual Volume (VV).
Estimated Available
Estimated available LUN storage. For HP 3PAR: LUN refers to Virtual Volume (VV).
Mount Point Used
The amount of storage used by each mount point.
Host
The name of the host to which the LUN was allocated. For HP 3PAR: LUN refers to Virtual Volume (VV).
Host LUN
The host LUN. For HP 3PAR: LUN refers to Virtual Volume (VV).
Mount Point
The host’s filesystem mount point for this LUN. It is possible to have zero mount points and filesystems, in the scenario where a LUN has been allocated to the host, but the host has not yet made use of it by creating a filesystem and mounting it. For HP 3PAR: LUN refers to Virtual Volume (VV).
Filesystem
The host’s filesystem or drive name to which the LUN maps. LUNs simply appear as disks to hosts. For HP 3PAR: LUN refers to Virtual Volume (VV).
Volume Group
The logical collection or volume group to which the volume belongs. For HP 3PAR: Volume group refers to Common Provisioning Group (CPG).
Host Storage Domain
The name of the host storage domain, a logical group of LUNs that can be accessed by multiple hosts through the same physical storage port, with each host accessing its unique LUN. For security purposes, LUN masking is also coupled with this capability. A host storage domain is Hitachi’s name for multi‑hosted storage capability. For HP 3PAR: LUN refers to Virtual Volume (VV).
Array Port WWN
Array port world wide name.
